The rebounding slider 2 is also internally provided with a tripping groove 23, a tripping block 24 is arranged in the tripping groove 23 in a sliding manner, one end of the tripping block 24 is contacted with the hook seat 211, the other end of the tripping block protrudes out of the right end face of the rebounding slider 2 to be contacted with the reset slider 3, and the reset slider 3 pushes the hook seat 211 to deflect through the tripping block 24 and is separated from the reset groove 19.

The base 1 on still be provided with the separating tank 6, install separation bullet piece 61 in the separating tank 6, be provided with separation spring 62 between separation bullet piece 61 and separating tank 6, separation spring 62 promotes separation bullet piece 61 and outwards releases, separation bullet piece 61 supports and presses on the slider 3 that resets, forces to reset and leaves the clearance of pressing between slider 3 and the slider 2 that rebounds.

The tension of the first tension spring 12 is greater than that of the second tension spring 13.

The hook base 211 is provided with a guide groove 214, the elastic hook 212 is telescopically mounted in the guide groove 214, and a spring is arranged between the guide groove 214 and the elastic hook 212 and always pushes the elastic hook 212 outwards.

The back of the hook seat 211 is provided with a guide sliding block 215, the guide sliding block 215 is positioned in the third guide rail 18 to slide, one side of the third sliding block, which is positioned in the reset groove 19, is provided with a hook groove 181, and after the hook seat 211 deflects to enter the reset groove 19, the guide sliding block 215 is clamped in the hook groove 181.

The second guide rail 14 is in a shape of an inverted "7", and the first hanging buckle block 31 is located on the second guide rail 14 to slide.

the working principle is as follows: as shown in fig. 1, which is an effect diagram of the closed state of the guide rail, in the closed state, the first hook block 31 is connected to the first hook 41 disposed on the guide rail 4, when a user needs to open the guide rail, the user presses the guide rail leftwards (inwards) with force and then releases his hand, the first hook pushes the reset slider 3 to move inwards, the reset slider squeezes the separation elastic block 61 and strikes the trip block 24, the inner end of the trip block 24 contacts with the hook seat 211, and when the trip block 24 moves inwards, the hook seat 211 is pushed to swing, so that the hook seat is separated from the reset groove 19 and enters the third guide rail 18. At this time, the rebounding slide block loses the positioning support, moves rightwards under the action of the second tension spring 13, and pushes the buffering slide block and the guide rail to rebound outwards and open.

As shown in fig. 4 and 8, when the guide rail reaches the maximum rebound stroke, the user needs to manually pull the drawer outwards, so as to connect the first hanging buckle block with the first hanging buckle 41 on the guide rail and pull the drawer outwards. When the first hanging-buckling block 31 moves to the rightmost end of the second guide rail 14, the first hanging-buckling block 31 deflects and is separated from the first hanging buckle 41, and the guide rail can be continuously opened outwards to the maximum stroke.

as shown in fig. 5 and 9, when the user needs to close the guide rail, the guide rail moves inward, the second hanging buckle 42 on the guide rail is connected with the second hanging block 53 arranged on the rebound slider 2, and the rebound slider 2 is pushed to move leftward (inward) when the guide rail is closed. When the rebound slider 2 moves leftwards (inwards), the second hanging block 52 arranged below the rebound pulling block 5 is connected with the hook 21 on the rebound slider 2, so that the rebound slider 2 is driven to move leftwards (inwards), and the first tension spring 12 and the second tension spring 13 are stretched to generate reset tension. When the rebounding slider moves inward to the maximum stroke, the hook seat 211 deflects after entering the reset groove 19 from the third guide rail 18, so that the elastic hook 212 is separated from the second hooking block 52, and the position of the rebounding slider is locked.

As shown in fig. 6, when the user continues to close the guide rail inward, the first hook 41 on the guide rail collides with the first hook block 31 and abuts against it, so that the first hook block 31 is separated from the rightmost end of the second guide rail 14, the buffer slider is unlocked, and the buffer slider moves leftward (inward) under the pulling of the first tension spring 12, thereby pulling the guide rail to close. In order to prevent the closing speed of the guide rail from being too high, a first buffer slide block 15 is further arranged on the second guide rail 14 to be in contact with the reset slide block 3, a buffer cylinder 16 is arranged on the base 1, and a piston rod 17 of the buffer cylinder 16 is connected with the first buffer slide block 15. When moving to the left, the damping slide is damped by the first damping slide 15, so that the guide rail is slowly closed.

Compared with the prior art, the guide rail in the present case has and presses the bounce-back to open, has the buffering during closing and resets and close the effect of back locking guide rail, when convenience of customers uses, promotes the user and uses feel, improves the product grade to have higher market competition.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above.
